Medrano is charged with using bribes to get business from Nebraska hospitals, prosecutors say.

Medrano, along with former Cook County Commissioner Joseph Moreno, was arrested in June and formally indicted last week in a 10-count indictment for accepting bribes to sell bandages to public hospitals.

Medrano was first elected to the Chicago City Council in 1991. Five years later, he was the first conviction in the Operation Silver Shovel investigation. He pleaded guilty to bribery charges after being confronted by officials who had him on video accepting $1,000 from a city contractor.

The former alderman, who was set free on bond last month, is set to appear again at the Dirksen U.S. Courthouse for arraigment on Wednesday for charges in his second bribery scheme.

Moreno is also expected to appear before a federal court Wednesday, the Tribune reports.
